WILLIAM CLIMIE, OFAYR, SCOTLAND.

. GAS-PRODUCER.

Specification of Letters Patent.

Application filed February 25, 1919; Serial No. 279,163.

To all whom it may concern." 1

Be it known that I, WILLIAM CnIMrn, a

subject of the King of Grreat Britain and Ireland and the 'Isle of Man, and ajre'sident of Ayr, Scotland, have invented new and; useful Improvements in Gas-Producers, of

which the following is a specification.

This in ventlon has reference "to improvements in and relating to" gas producers,- comprises an improved arrangement" and construction of appliances 5 arranged within the producer for raking'and bre'akingup the fuel so that satisfactory results may be" ob} tained when using'fuel which has a tendency to cake in the producer. 1

WVhen using this caking fuel it has been found in practice that'a crust is formed over the fuel and when the ashes'are removed from below. the green expanded fuel does" not follow which necessitates the application of such appliances for the prevention of channeling through the incandescent fuel.

The object of this invention is to provide a rake which will prevent the formation of this crust so that the full output of gas is obtained from the fuel and all the fuel steadily and automatically finds its way down through the producer through the various zones to the ash pit where the refuse is removed.

According to this invention the rake referred to comprises a crosshead adapted to slide vertically on and to be rotated by a central shaft. This crosshead is provided with appliances comprising toothed rollers adapted to roll on the Surface of the fuel and crush the crust of same and teeth adapted to rake up and spread the top surface of the fuel while longer teeth or knives may also be provided to tear through and break up the fuel. A scraper blade may also be arranged and adapted to keep clear the up per surface of the cone shaped air inlet at the lower part of the producer.

In order that others skilled in the art to which this invention relates may properly understand the same I have hereunto appended two sheets of explanatory drawings in which Figures 1 and 2 are respectively elevations at right angles to each other of a rake constructed according to the improvements of this invention, with the producer casing shown broken away.

Referring to said drawings t In carrying the improvements of th1s 1nvention into eflect or practice a crosshead a is slidably iinounted on a vertical shaft 1) arranged centrally in the producer a. This shaft 2) is rotated at the desiredspeed by suitable driving means, such as gear Wheels Z) and b driven from a'primemoving shaft 6 arranged above the,

producer. The shaft I) is of hexagonalor. other,

pqlygqmlshape insection. soth'at'as the shaftl 1s rotated the'crosshead afis rotated.

also while the crosshead is cap-able of slidingvertically upv and down on the j said shaft '5'. v

This crosshead is preferably formed in twoparts secured together by bolts or. the

like 03 passing'through flanges or lugs e on each part. Horizontally projecting rodsrf aresec'ure'd to the crosshead a,' preferablytwo, diametrically opposite each other, and these rods are provided with toothed rollers g which rest onthe fuel andare rotated on their rods f by their teeth it gripping or digging into the fuel as the crosshead a is rotated by the central shaft Z). It will thus be seen that the rollers 9 travel over the surface of the fuel and as there are three rollers arranged at different distances from the central shaft Z) it will also be seen that the full surface of the fuel is operated upon.

Other rods, bars or the like i are also se. cured to the crosshead a preferably two rods diametrically opposite each other and at right angles to the rods f carrying the rollers 9. These latter rods z are provided with plates or the like j having downwardly projecting teeth or the like 7:: so that. the said latter rods and plates are rotated around the central shaft 6 by means of the crosshead a the teeth It rake up the upper surface of the fuel and scatter or spread same. The plates 7' are preferably loosely mounted on the rods 2' so that should. the teeth 7:: meet a hard or stiff piece or cake of fuel they will riseup and mount or be dragged over that hard piece. The rods '5 may also be provided with a plurality of downwardly projecting long teeth or knives Z fixed on the shaft to assist in preventing the formation of the crust or cake by cutting or tearing through the fuel to a suitable depth. There are preferably three of these long teeth or knives Z.

The, lower end of the central shaft 6 may also be provided with a crosshead m having a scraper blade or knife n which as the shaft 6 is rotated passes over the upper surface of the central cone 0 usually cara'tented Jan. 13, 1920. i

ranged at the bottom of the producer and the rake) rests and operates upon the surface of the fuel which slowly falls down the producer as gasification takes place and the refuse is withdrawn in the usual manner and upon a fresh charge of fuel being introduced into the producer from above the rollers cause the rake to mount over the fresh fuel so that the rake automatically maintains its position on the top of the fuel.

What I claim and desire to secure by Letters Patent is 1. A gas producer comprising a: casing, a fuel rake arranged therein, a device for imparting a traveling movement to said rake over the surface of the fuel, and toothed crushing rolls carried by the rake structure, said rolls tending to maintain the rake at the top surface of the fuel and to crush the crust thereof.

2. A gas producer comprising a casing, a fuel rake having teeth arranged to penetrate the top surface of the fuel and having toothed crushing rolls rotatably mounted on the rake structure, said rolls tending to maintain the rake at the top surface of the fuel and to crush the crust thereof.

3. A gas producer comprising a casing, a vertical shaft disposed therein, a crosshead mounted on said shaft and having outwardly extending arms, teeth on one of said arms, and toothed rolls on another of said arms.

l. A gas producer comprising a casing, a

- central shaft therein, a crosshead on said shaft having four radial arms extending therefrom, one pair of opposite arms having toothed rollers thereon and the other pair of arms having teeth.

5. A gas producer comprising a casing, a vertical shaft disposed therein, a crosshead having four uniformly-spaced arms extending therefrom mounted and adapted to be rotated upon said shaft, teeth upon one pair of oppositely disposed arms, and toothed crushing rolls upon the other pair of oppositely disposed arms, said rolls being arranged at different distances from the center of rotation of said crosshead.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.

WILLIAM GLIMIE.
